    Syntax:

  #include &lt;sstream&gt;

  operator&gt;&gt;
</pre>

  <p>Like <a href="../cppio/index.html">C++
  I/O Streams</a>, the simplest way to use string streams is to take
  advantage of the overloaded &lt;&lt; and &gt;&gt; operators.</p>

  <p>The &lt;&lt; operator inserts data into the stream.  For
  example:</p>

  <pre class="example-code">
  stream1 << "hello" << i;
</pre>

  <p>This example inserts the string "hello" and the variable <i>i</i>
  into <i>stream1</i>.  In contrast, the &gt;&gt; operator extracts
  data out of a string stream:</p>

  <pre class="example-code">
  stream1 >> i;
</pre>

  <p>This code reads a value from <i>stream1</i> and assigns the
  variable <i>i</i> that value.</p>
